There are many fine points to learn regarding the TDR use. I think the most
valuable thing you can do at this point is to play with it. Presumably you
have no pressing need for this and you can take your time familiarizing
yourself with not only the controls, but the documentation and physics of what
you're looking at. Go through the "First Time Operation" section of the
manual. Review the Calibration section, study the schematics, but don't worry
about knowing it all yet. Just get familiar with it. Maybe order a hardcopy
from your favorite auction site?
Build up appropriate hardware - having good/proper accessories goes a long way
toward making the equipment easier to use. Build different lengths of cable,
see what effects they have. Look at waveforms with and without termination.
Get to know what does what. I tested all my SMA and BNC connectors and
discovered I had a batch of 75ohm T's, not 50ohm. Friggin' Amazon. Caveat
emptor. But it's all qualitative at this point. Get a good feel for the
qualitative stuff first.
Have fun! Great find!

Thanks Dave.
Yes, at this point I¡¯m just playing with it, and I will keep doing so until I become more proficient with it.
I also saw that the Type 106 calibration procedure calls for the use of a sampling scope. Maybe I¡¯ll be able to use this for that purpose¡?
Cheers
